GEORGE G. BESSONET, OF CHICAGO, ILLINOIS.

MUSIC-HOLDER.

Specification of Letters Patent.

Application filed January 11, 1916. Serial No. 71,455.

To all whom it may concern:

Be it known that I, GEORGE C. BESSONET, a citizen of the United States, and a resident of the city of Chicago, county of Cook, and State of Illinois, have invented certainnew and useful Improvements inhilusic-Holders, of which the following is a specification.

My invention relates to improvements in music holders, and has for its object the provision of an improved construction of this character which is capable of exhibiting successively sheets of music or the like and which is easily operable and eflicient in use.

/ The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings forming a part of this specification, and in which,

Figure 1 is a face view embodying my invention,

Fig. 2, a similar view with portions reof a construction -moved to show the interior working parts,

Fig. 3, a horizontal section taken through the construction, V

Fig. 4, a vertical section taken through the construction, and

Fig. 5, an enlarged partial vertical section taken through the construction and illustrating more articularly the reversing mechanism empl byed therein.

The preferred form of construction, as illustrated in the drawings comprises a suit able casing 6 having removable face or cover portions 7, 8 and 9 giving access to the interior thereof. Guides 10 and 11 are positioned on cover member 7 to constitute guides for the edges of a continuous strip of pa er 12-wound upon a detachable spool or ro ler 13 and assing across the face of cover member 7 and windable onto a permanently mounted spool or roller 14, as will be readily understood. The strip 12is printed with the successive pages of a piece of music or the like, said pages being arranged transversely with respect to the length of said strip with the tops of the pages corresponding with the upper edge of said strip so that as said strip is moved across the cover plate 7 from right to left in Fig. 1, the successive pages of music will be successively presented to view, as will be readily understood.

The detachable roller 13 is operated through the medium of a bevel gear 15 of a spring 25 of any'usual or desired form PatentedAug. 12, 1919.

of clock spring mechanism, as will be readi ily understood. The usual winding stem 26 is provided for winding up spring; 25. Upstanding stop pins 27 arearranged on gear 24 and cooperate with a sprin plunger 28 operable by means of .an operating lever 29. The pins 27 are so positioned and the other parts arranged so that upon momentary withdrawal of plunger '28, the

held stop crown gear 24 is released and will operate through an arc of a circle until the next pin 27 encounters the plunger 28. l/Vith gear 18 shifted into mesh with gear 19 this partial rotation of crown gear 24 will efiect operation of roller or spool 14 to cause feeding of the strip 12 to present the first page of music thereon. After this subsequent operations of lever 29 will efiect presentation of the successive'pages of music printed on strip 12 and automatic stopping of the same in cen tral position on cover member 7, as will be readily understood.

At one end the elongated gear 20 is pro vided with an annular groove 30 engaged by a pin 31 onan operating lever 32 projecting through a slot 33 in cover plate 7 A latching lever 34' is provided with notches 35 and 36 arranged to be swung into engagement with lever 32 when said lever is shifted into position to bring gear 16 or 18 into operative engagement with the corresponding gear 15 or 19 as the case may be. By this arrangement when all of the pages of the piece or pieces of music have been successivel y presented, as explained above, the shaft 17 is shifted to the right, as indicated in Fig. 2, to bring gear 16 into mesh with gear 15 and lever 29 withdrawn and held in withdrawn position, whereupon spring 25 will operate to effect continuous rewinding of the strip 12. Then the roller or spool 13 may be removed and another roller bearing Spring operating brakes 37 and 38 are secured respectively to the under sides of cover members 8 and 9 in positions to ofier resistance to the rotations of rollers 1-1 and 13 respectively. Each of these brake members cooperates with a corresponding bell crank lever 39 and L0 respectively, and operating pins or arms 41 and 42 are arranged on shaft 17 to cooperate with said bell cranks and whereby shifting of said shaft to the right causes release of the braking pressure of brake member 38 and application of braking pressure by brake member 37. Likewise shifting by said shaft to the left causes release of the brake member 37 and application of the brake member 88. It will also be observed, that the arrangement is suchthat in each instance the braking resistance is applied to the roller which is at the time unwinding thus preventing spinning of said roller and insuring a tight and neat winding thereof upon the roller which happens at the time to be the active or winding roller.

The casing 6 is also provided with two adjustable supporting legs 4-8 having rubber feet or rests 44: adapted to support the casing on the usual music rack of a piano, said legs being rendered adjustable by means of binding nuts 45 operating through longitudinal slots therein, as will be readily imderstood. The casing 6 is also equipped with a suspending member 46 having a securing foot 47 adapted to be secured to the upper portion of the piano and thus serve as a means for securing the casing in place and preventing accidental displacements thereof.

While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is ca iable of variation and modification without c eparting from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

Having described my invention what I claim as new and desire to secure by Letters Patent is:

1. A device of the class described comprising a casing; two rollers mounted on said casing; a continuous strip of flexible material wound on one roller and windable onto the other roller; a bevel gear arranged to operate each of said rollers; a longitudinally shiftable shaft carrying bevel gears arranged to be shifted into mesh with either of the roller-driven bevel gears; 'a clock spring mechanism; a gear operable by said clock spring mechanism; pins projecting from the face of said gear; a spring-held plunger arranged to engage said pins to prevent rotation of the gear carrying the same; and an operative connection between said pin-carrying gear and said longitudinally shiftable shaft, substantially as described.

2. A device of the class described comprising a casing; two rollers mounted on said casing; a continuous strip of flexible material wound on one roller and windable onto the other roller; a bevel gear arranged to operate each of said rollers; a longitudinally shiftable shaft carrying bevel gears arranged to be shifted into mesh with either of the roller-driven bevel gears; means for operating said longitudinally shiftable shaft; and brake mechanism for each of said rollers, automatically operable by longitudinal shifting of said longitudinally shiftable shaft to apply resistance to the unwinding roller, substantially as described.

3. A device of the class described comprising a casing; two rollers mounted on said casing; a continuous strip of flexible material wound on one roller and windable on the other, said strip being divided into pages; guides for said strip; a bevel gear arranged to operate each of said rollers; a longitudinally shiftable shaft carrying bevel gears arranged to be shifted into mesh with either of the roller driving bevel gears; a clock spring mechanism; a crown gear operable by said clock spring mechanism; pins Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents, Washington, D.
